    Description: A DNA sequence coding for the immunogenic capsid protein VP3 of foot-and-mouth disease virus A12, prepared from the virion RNA, was ligated to a plasmid designed to express a chimeric protein from the Escherichia coli tryptophan promoter-operator system. When Escherichia coli transformed with this plasmid was grown in tryptophan-depleted media, approximately 17 percent of the total cellular protein was found to be an insoluble and stable chimeric protein. The purified chimeric protein competed equally on a molar basis with VP3 for specific antibodies to foot-and-mouth disease virus. When inoculated into six cattle and two swine, this protein elicited high levels of neutralizing antibody and protection against challenge with foot-and-mouth disease virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleid, D G -- Yansura, D -- Small, B -- Dowbenko, D -- Moore, D M -- Grubman, M J -- McKercher, P D -- Morgan, D O -- Robertson, B H -- Bachrach, H L -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1125-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6272395" target="_blank"〉PubMed〈/a〉

    Description: The generally mild bleeding disorder of von Willebrand disease is associated with abnormalities of two distinct plasma proteins, the large multimeric von Willebrand factor (vWF), which mediates platelet adhesion, and von Willebrand antigen II (vW AgII), which is of unknown function. The two proteins were found to have a common biosynthetic origin in endothelial cells and megakaryocytes, which explains their simultaneous absence in the severe form of this hereditary disease. Shared amino acid sequences from a 100-kilodalton plasma glycoprotein and from vW AgII are identical to amino acid sequences predicted from a complementary DNA clone encoding the 5' end of vWF. In addition, these proteins have identical molecular weights and immunologic cross reactivities. Monoclonal antibodies prepared against both proteins recognize epitopes on the pro-vWF subunit and on a 100-kilodalton protein that are not present on the mature vWF subunit in endothelial cell lysates. In contrast, polyclonal antibodies against vWF recognize both pro-vWF and vWF subunits. Thus, the 100-kilodalton plasma glycoprotein and vW AgII are identical proteins and represent an extremely large propolypeptide that is first cleaved from pro-vWF during intracellular processing and then released into plasma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fay, P J -- Kawai, Y -- Wagner, D D -- Ginsburg, D -- Bonthron, D -- Ohlsson-Wilhelm, B M -- Chavin, S I -- Abraham, G N -- Handin, R I -- Orkin, S H -- HL-30616/HL/NHLBI NIH HHS/ -- HL-34050/HL/NHLBI NIH HHS/ -- HL-34787/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 May 23;232(4753):995-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3486471" target="_blank"〉PubMed〈/a〉

    Description: CD4 is a cell surface glycoprotein that is thought to interact with nonpolymorphic determinants of class II major histocompatibility (MHC) molecules. CD4 is also the receptor for the human immunodeficiency virus (HIV), binding with high affinity to the HIV-1 envelope glycoprotein, gp120. Homolog-scanning mutagenesis was used to identify CD4 regions that are important in class II MHC binding and to determine whether the gp120 and class II MHC binding sites of CD4 are related. Class II MHC binding was abolished by mutations in each of the first three immunoglobulin-like domains of CD4. The gp120 binding could be abolished without affecting class II MHC binding and vice versa, although at least one mutation examined reduced both functions significantly. These findings indicate that, while there may be overlap between the gp120 and class II MHC binding sites of CD4, these sites are distinct and can be separated. Thus it should be possible to design CD4 analogs that can block HIV infectivity but intrinsically lack the ability to affect the normal immune response by binding to class II MHC molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamarre, D -- Ashkenazi, A -- Fleury, S -- Smith, D H -- Sekaly, R P -- Capon, D J -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):743-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Immunologie, Institut de Recherches Cliniques de Montreal, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549633" target="_blank"〉PubMed〈/a〉

    Description: The ability to clone large fragments of DNA in yeast artificial chromosomes (YAC's) has created the possibility of obtaining global physical maps of complex genomes. For this application to be feasible, most sequences in complex genomes must be able to be cloned in YAC's, and most clones must be genetically stable and colinear with the genomic sequences from which they originated (that is, not liable to undergo rearrangement). These requirements have been met with a YAC library containing DNA fragments from Drosophila melanogaster ranging in size up to several hundred kilobase pairs. Preliminary characterization of the Drosophila YAC library was carried out by in situ hybridization of random clones and analysis of clones containing known sequences. The results suggest that most euchromatic sequences can be cloned. The library also contains clones in which the inserted DNA is derived from the centromeric heterochromatin. The locations of 58 clones collectively representing about 8 percent of the euchromatic genome are presented.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garza, D -- Ajioka, J W -- Burke, D T -- Hartl, D L -- New York, N.Y. -- Science. 1989 Nov 3;246(4930):641-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Washington University School of Medicine, St. Louis, MO 63110-1095.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2510296" target="_blank"〉PubMed〈/a〉

    Description: Three cellular homologs of the v-erbA oncogene were previously identified in the rat; two of them encode high affinity receptors for the thyroid hormone triiodothyronine (T3). A rat complementary DNA clone encoding a T3 receptor form of the ErbA protein, called r-ErbA beta-2, was isolated. The r-ErbA beta-2 protein differs at its amino terminus from the previously described rat protein encoded by c-erbA beta and referred to as r-ErbA beta-1. Unlike the other members of the c-erbA proto-oncogene family, which have a wide tissue distribution, r-erbA beta-2 appears to be expressed only in the anterior pituitary gland. In addition, thyroid hormone downregulates r-erbA beta-2 messenger RNA but not r-erbA beta-1 messenger RNA in a pituitary tumor-derived cell line. The presence of a pituitary-specific form of the thyroid hormone receptor that may be selectively regulated by thyroid hormone could be important for the differential regulation of gene expression by T3 in the pituitary gland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodin, R A -- Lazar, M A -- Wintman, B I -- Darling, D S -- Koenig, R J -- Larsen, P R -- Moore, D D -- Chin, W W -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):76-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539642" target="_blank"〉PubMed〈/a〉

    Description: Hybridoma technology has made it possible to introduce into continuous culture normal antibody-forming cells and to obtain large amounts of the immunoglobulin produced by each of these cells. Examination of the structure of a number of monoclonal antibodies that react with a single antigen has provided new information on the structural basis of the specificity and affinity of antibodies. Comparisons of families of monoclonal antibodies derived from a single germ line gene revealed the importance of somatic mutation in generating antibody diversity. Monoclonal antibodies that react with variable regions of other monoclonals allow the further dissection and modulation of the immune response. Finally, the continued somatic instability of immunoglobulin genes in cultured antibody-forming cells makes it possible to determine the rate of somatic mutation and to generate mutant monoclonal antibodies that may be more effective serological reagents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teillaud, J L -- Desaymard, C -- Giusti, A M -- Haseltine, B -- Pollock, R R -- Yelton, D E -- Zack, D J -- Scharff, M D -- 5T32GM7288/GM/NIGMS NIH HHS/ -- AI05231/AI/NIAID NIH HHS/ -- AI10702/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1983 Nov 18;222(4625):721-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6356353" target="_blank"〉PubMed〈/a〉

    Description: The primary structure of human uromodulin, a 616-amino acid, 85-kilodalton glycoprotein with in vitro immunosuppressive properties, was determined through isolation and characterization of complementary DNA and genomic clones. The amino acid sequence encoded by one of the exons of the uromodulin gene has homology to the low-density-lipoprotein receptor and the epidermal growth factor precursor. Northern hybridization analyses demonstrate that uromodulin is synthesized by the kidney. Evidence is provided that uromodulin is identical to the previously characterized Tamm-Horsfall glycoprotein, the most abundant protein in normal human urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pennica, D -- Kohr, W J -- Kuang, W J -- Glaister, D -- Aggarwal, B B -- Chen, E Y -- Goeddel, D V -- New York, N.Y. -- Science. 1987 Apr 3;236(4797):83-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3453112" target="_blank"〉PubMed〈/a〉

    Description: In a study of the immunologic significance of the genetic diversity present within single isolates of human immunodeficiency virus type 1 (HIV-1), the neutralization of viruses derived from molecular clones of the HIV-1 strain HTLV-IIIB by an extensive panel of sera was compared. Sera from HIV-1-infected patients and from goats immunized with polyacrylamide gel-purified HIV-1 envelope glycoprotein (gp120), native gp120, or gp120-derived recombinant peptides, showed marked heterogeneity in neutralizing activity against these closely related viruses. The change of a single amino acid residue in gp120 may account for such "clonal restriction" of neutralizing activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Looney, D J -- Fisher, A G -- Putney, S D -- Rusche, J R -- Redfield, R R -- Burke, D S -- Gallo, R C -- Wong-Staal, F -- New York, N.Y. -- Science. 1988 Jul 15;241(4863):357-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Viral Diseases, Walter Reed Army Institute of Research, Washington, DC 20307.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3388046" target="_blank"〉PubMed〈/a〉

    Description: Fifteen independently isolated complementary DNA clones that contain T-cell receptor (TCR) V beta genes were sequenced and found to represent 11 different V beta genes. When compared with known sequences, 14 different V beta genes could be defined from a total of 25 complementary DNA's; 11 clones therefore involved repeated usage of previously identified V beta's. Based on these data, we calculate a maximum likelihood estimate of the number of expressed germline V beta genes to be 18 with an upper 95 percent confidence bound of 30 genes. Southern blot analysis has shown that most of these genes belong to single element subfamilies which show very limited interstrain polymorphism. The TCR beta-chain diversity appears to be generated from a limited V beta gene pool primarily by extensive variability at the variable-diversity-joining (V-D-J) junctional site, with no evidence for the involvement of somatic hypermutation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behlke, M A -- Spinella, D G -- Chou, H S -- Sha, W -- Hartl, D L -- Loh, D Y -- GM07200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Aug 9;229(4713):566-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3875151" target="_blank"〉PubMed〈/a〉

    Description: The myb gene is the transforming oncogene of the avian myeloblastosis virus (AMV); its normal cellular homolog, c-myb, is conserved across a broad span of evolution. In humans, c-myb is expressed in malignant hematopoietic cell lines and in primary hematopoietic tumors. Partial complementary DNA clones were generated from blast cells of patients with acute myelogenous leukemia. The sequences of the clones were compared to the c-myb of other species, as well as the v-myb of AMV. In addition, the carboxyl terminal region of human c-myb was placed in an expression vector to obtain protein for the generation of antiserum, which was used to identify the human c-myb gene product. Like v-myb, this protein was found within the nucleus of leukemic cells where it was associated with the nuclear matrix. These studies provide further evidence that c-myb might be involved in human leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- Boone, T C -- Murdock, D C -- Keith, D E -- Press, M F -- Larson, R A -- Souza, L M -- CA36827/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jul 18;233(4761):347-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014652" target="_blank"〉PubMed〈/a〉
